When INC transitions from high-to-low, the wiper moves in the direction established by the state of the U/D pin. 2U/D Up/Down Control. Sets the directions of wiper movement. When set to a high state, a high-to-low transition on the INC pin increments the wiper. When set to a low state, a high-to-low transition on the INC pin decrements the wiper. 3 H High-End Terminal of the Potentiometer 4 GND Ground Terminal 5 W Wiper Terminal of the Potentiometer 6 L Low-End Terminal of the Potentiometer 7 CS Chip Select. When set to a low state, the wiper position can be adjusted using U/D and INC. When in a high-state, activity on INC and U/D does not affect or change the wiper position. 8VCC Power Supply Terminal |
